This paper discusses techniques for pattern induction and matching in musical audio. At all levels of music - harmony, melody, rhythm, and instrumentation - the temporal sequence of events can be subdivided into shorter patterns that are sometimes repeated and transformed. Methods are described for extracting such patterns from musical audio signals (pattern induction) and computationally feasible methods for retrieving similar patterns from a large database of songs (pattern matching).
